Is there any reason to create a new module instead of putting the
package into "music.scm"?

This line is too long. Moreover, I think "PREFIX=" is not necessary, as
Guix adds it automatically. I'm not sure about "PREFIXSHORTCUT=", tho.

It seems PREFIX and PREFIXSHORTCUT are used in qmake, not in make, so it
may be possible to remove the whole #:make-flags altogether. WDYT?

Indentation looks wrong. Could you take care about it?

The line is too long. I suggest:

  (let ((out (assoc-ref %outputs "out")))
    (invoke "qmake"
            "fmit.pro"
            (string-append "PREFIX=" out)
            (string-append "PREFIXSHORTCUT=" out)
            "CONFIG+=acs_qt acs_alsa acs_jack acs_portaudio"))

Could you re-order (native-)inputs alphabetically?

I understand Free is the F from FMIT, but, as a synopsis, I don't think
it brings much value. Maybe "Musical instrument tuner" is enough?

Prefer https:// here.

> +    (license gpl3+)))

If you move it to music.scm, I believe it should be prefixed with
license:

Also, the license seems wrong, it should be (list license:gpl2+
license:lgpl2.1) with a comment explaining that most of the code is
under GPL2+, but some abstract or helper classes are under LGPL2.1.
